ReachMedia: MIT wants to know what you're fingering

Imagine the ability to do an automatic froogle price comparison on that digital camera you are lustfully fingering
at the shop. To this end, MIT researchers propose a system dubbed ReachMedia which includes a ReachBand (read:
bracelet) with accelerometer and RFID reader to respond to hand gestures and detect the tagged object you are holding.
An Internet-connected cellphone responds with an alert which indicates that information is available and then provides
that information audibly. A flick of the hand would then signal a request for more information. Yes, mongers of doom,
this could work for humans too.
